The Ell is an historical unit of length, primarily used for measuring cloth and textiles. Its exact length varied considerably depending on the region, country, and time period, making it a non-standardized unit overall, though often legally defined within specific jurisdictions.
It is generally understood to have originated from the length of the arm or forearm, similar to the cubit. The name itself derives from the Proto-Germanic word *alinō, meaning "forearm".
Common historical values demonstrate this variability:
- English Ell: Traditionally 45 inches (1.25 yards, exactly 1.143 meters). This was the most common ell in England, particularly for measuring imported Flemish cloth.
- Scottish Ell: Approximately 37.06 inches (about 0.941 meters), based on the standard Scottish inch.
- Flemish (or Brabant) Ell: Approximately 27 inches (about 0.686 meters). Widely used in the Low Countries, a major center for textile production.
- French Ell (Aune): Varied, but often around 46.77 inches (about 1.188 meters) in Paris. The aune itself had different lengths in different French regions.
- Polish Ell (Łokieć): Approximately 22.7 inches (about 0.576 meters).
- Swedish Ell (Aln): Approximately 23.3 inches (about 0.593 meters).
The centimeter (symbol: cm) is a unit of length equal to exactly one-hundredth of a meter (1/100 m or 0.01 m). It's also equal to exactly 10 millimeters.
The centimeter is part of the International System of Units (SI) and uses the metric prefix "centi-" meaning one-hundredth (from Latin centum, "hundred").
Mathematical Relationships
1 centimeter equals:
- 10 millimeters (mm)
- 0.01 meters (m)
- 0.00001 kilometers (km)
- 0.393701 inches (in)
- 0.0328084 feet (ft)
Key conversion:
- 1 inch = 2.54 cm exactly (this is the official international definition established in 1959)
Why Centimeters?
While the meter is the official SI base unit for length, centimeters are more practical for everyday measurements:
Too small for meters, too large for millimeters: A person who is 1.75 meters tall is more commonly described as 175 centimeters in metric countries. Writing "1.75 m" requires decimals; "175 cm" uses whole numbers.
Human-scale convenience: Most objects people interact with daily—clothing, screens, body measurements, food items—fall naturally into the 1-100 cm range.
Avoids decimal confusion: "15.2 cm" is clearer than "0.152 m" for most people.
Note: The Ell is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Centimeter belongs to the metric (SI) system.
History of the Ell and Centimeter
The ell was a fundamental unit for the textile trade across Europe, flourishing from the medieval period through the early modern era and into the 19th century. Its origins likely lie in anthropomorphic measurements related to the arm, similar to the cubit.
The lack of a universal standard led to numerous regional variations. Different cities, guilds, or nations established their own "standard" ell, often physically represented by a metal rod kept by authorities. This variation could sometimes be a source of trade disputes but also reflected local manufacturing and trade practices.
The English ell of 45 inches (longer than the standard English yard of 36 inches) became particularly well-established, possibly to account for shrinkage or to provide a customary "bonus" measure when selling cloth.
With the rise of standardized measurement systems like the Imperial system (promoting the yard) and especially the Metric system (introducing the meter), the ell gradually became obsolete during the 18th and 19th centuries. Legal reforms in many countries formally abolished it in favor of metric units.
French Revolution and the Birth of the Metric System
1790s: Revolutionary Innovation: The centimeter was born from the French Revolution's ambition to create a rational, universal measurement system based on nature and decimal mathematics.
The Meter Foundation: In 1791, the French Academy of Sciences defined the meter as one ten-millionth (1/10,000,000) of the distance from the equator to the North Pole along the meridian passing through Paris. The centimeter automatically followed as 1/100 of this meter.
Latin Roots: The prefix "centi-" derives from the Latin centum (hundred), making "centimeter" literally "hundredth of a meter."
1795 Official Adoption: France officially adopted the metric system on April 7, 1795, including the centimeter as a standard subdivision of the meter.
CGS System: The Centimeter's Scientific Era
1874: The Centimeter-Gram-Second System: British scientists James Clerk Maxwell and William Thomson (Lord Kelvin) promoted the CGS system, which used:
- Centimeter for length (instead of meter)
- Gram for mass (instead of kilogram)
- Second for time
Scientific Dominance: The CGS system became the preferred standard for physics and chemistry throughout the late 19th and early 20th centuries. Many scientific formulas and units were developed using centimeters.
Legacy Units: Several units still reflect the CGS heritage:
- Poise (viscosity): measured in gram/(centimeter·second)
- Erg (energy): gram·centimeter²/second²
- Gauss (magnetic field): CGS unit for magnetic flux density
Transition to SI and the Modern Era
1960: The SI System: The International System of Units (SI) was officially established, promoting the meter-kilogram-second (MKS) system instead of CGS.
Centimeter's Continued Relevance: Despite the official SI preference for meters, centimeters remained dominant for everyday measurements because:
- They're more practical for human-scale objects
- They avoid decimals for most common measurements
- They're familiar and intuitive
Global Adoption: Today, 195 of 198 countries use the metric system, with centimeters as the standard for body height, clothing, and everyday measurements. Only the United States, Myanmar, and Liberia officially use non-metric systems.
Common Uses and Applications: ells vs centimeters
Explore the typical applications for both Ell (imperial/US) and Centimeter (metric) to understand their common contexts.
Common Uses for ells
The ell is now obsolete but was historically crucial for:
- Textile Trade: Its primary and defining use was measuring and selling lengths of cloth (wool, linen, silk, etc.). Cloth was often priced and sold "by the ell".
- Tailoring and Dressmaking: Used by artisans creating garments.
- Mercantile Records: Appears frequently in historical merchant accounts, inventories, customs documents, and trade records. Understanding the local ell is vital for interpreting these economic historical sources.
- Land Measurement (Rarely): In some specific, localized contexts, an ell might have been used for land, but this was uncommon compared to units like the rod or chain.
- Literature and Culture: Referenced in historical texts, literature, and idioms (e.g., "Give him an inch, and he'll take an ell").

Additional Unit Information
About Ell (ell)
How long is an Ell?
There is no single fixed length for the ell; it varied significantly by location and time. Some key examples include:
- English Ell: 45 inches (1.143 m)
- Scottish Ell: ~37 inches (~0.94 m)
- Flemish Ell: ~27 inches (~0.69 m)
- French Aune (Ell): ~47 inches (~1.19 m) Always check the context (region and era) when encountering a measurement in ells. The English ell of 45 inches is often assumed in English-language historical contexts unless otherwise specified.
How does the Ell compare to a Yard?
The English ell (45 inches) is exactly 1.25 times longer than the standard yard (36 inches). However, other ells could be shorter (like the Flemish ell) or have different relationships to the local yard equivalent.
Is the Ell related to the Elbow or Arm?
Yes, the name "ell" derives from Proto-Germanic *alinō ("forearm"), cognate with Latin ulna and Greek ōlénē, all referring to the forearm or elbow. This strongly suggests an origin based on the length of the human arm, similar to the cubit. However, the standardized lengths adopted for trade were often considerably longer than a literal forearm.
Why did the Ell length vary so much?
The variation stemmed from:
- Lack of Universal Standards: Before the metric system, measurement standards were highly localized.
- Regional Customs: Different areas developed their own traditional lengths based on local needs and practices.
- Trade Protectionism: Sometimes, variations were maintained deliberately by guilds or cities.
- Evolution Over Time: The definition could change even within the same region over centuries.
Is the Ell an SI unit?
No, the ell is not part of the International System of Units (SI). It is an historical, customary unit belonging to various pre-metric systems. The corresponding SI unit for length is the meter (m).
Is the Ell still used today?
No, the ell is obsolete and is not used for any standard commercial, scientific, or practical measurements today. Its use was superseded primarily by the yard (in Imperial/US customary systems) and the meter (in the metric system). Its relevance is now purely historical.
